Compare Two RadDatePickers in RadGrid

[Mike]

I have a RadGrid that has two RadDatePickers.  There is a start and end date RadDatePicker. 

How can I validate that a user must pick an end date is greater than the start date.

Hello MIchael,

You can compare RadDatePickers using CompareValidator as shown below. Hope this helps.

aspx:

<telerik:GridTemplateColumn>
    <EditItemTemplate>
        Start:
        <telerik:RadDatePicker  ID="RadDatePicker1" runat="server">
        </telerik:RadDatePicker>
    </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn>
    <EditItemTemplate>
        End:
        <telerik:RadDatePicker ID="RadDatePicker2" runat="server">
        </telerik:RadDatePicker>
        <asp:CompareValidator ID="CompareValidator1" Operator="GreaterThan" ControlToValidate="RadDatePicker2" ControlToCompare="RadDatePicker1" ErrorMessage="EndDate must be greater than StartDate" runat="server"></asp:CompareValidator>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

Thanks,
Princy.
